This study aimed to reassess the effect of prophylactic transcervical amnioinfusion for intrapartum meconium-stained amniotic fluid. The results showed that amnioinfusion significantly reduces the odds of meconium aspiration syndrome and other adverse neonatal outcomes.
OBJECTIVE: This study aimed to reassess the effect of prophylactic transcervical amnioinfusion for intrapartum meconium-stained amniotic fluid on meconium aspiration syndrome and other adverse neonatal and maternal outcomes. DATA SOURCES: From inception to November 2021, a systematic search of the literature was performed in PubMed, Embase, Web of Science, and Scopus databases and gray literature sources. STUDY ELIGIBILITY CRITERIA: We identified randomized controlled trials of patients with intrapartum moderate to thick meconium-stained amniotic fluid that evaluated the effect of amnioinfusion on adverse neonatal and maternal outcomes. METHODS: Of note, 2 reviewers independently abstracted data and gauged study quality by assigning a modified Jadad score. Meconium aspiration syndrome constituted the primary outcome. The secondary outcomes were meconium below the cords, Apgar scores of <7 at 5 minutes, neonatal acidosis, cesarean delivery, cesarean delivery for fetal heart rate abnormalities, neonatal intensive care unit admission, and postpartum endometritis. This study calculated the odds ratios with 95% confidence intervals for categorical outcomes and weighted mean differences with 95% confidence intervals for continuous outcomes. RESULTS: A total of 24 randomized studies with 5994 participants met the inclusion criteria. The overall odds of meconium aspiration syndrome was reduced by 67% in the amnioinfusion group (pooled odds ratio, 0.33; 95% confidence interval, 0.21-0.51). Except for postpartum endometritis, amnioinfusion was associated with a significant reduction in all secondary outcomes. CONCLUSION: Our study found that the use of intrapartum amnioinfusion in the setting of meconium-stained amniotic fluid significantly reduces the odds of meconium aspiration syndrome and other adverse neonatal outcomes.
